DUMP-CAR-GONTROL MECHANISM.

present invention used on dump cars for controlling the dumping of the lading in said cars.

Certain dumplng mechanisms as now known and used are open to objectionby reason of the is liable to lodge in parts of interfering with mechanism,

fact that lading .the operating the proper functioning thereof and requiring considerable personal attention on the part of the operators of said mechanism.

A further oh ect1on to certain dumping mechanism as now the fact that certain of are liable to assume positions,

The numeral 1 indicates car of the selective type.

vided with side walls 2-2 a railway dump Said car is pro and a center sill 3. The center sill 3 is provided with a cope 4: and with shedding ing lading transversely walls 5-5 for direct of the car away .asmuch as the details of Serial No. 873,876.

from the center sill 3. Mounted adjacent the side walls are the sloping walls 6-6, which converge downwardly and inwardly of the car. Pivoted for movement about the axes 7-7 are dump doors 8-8 which co-operate with the walls 6-6 and shedding walls 5-5 to complete the closure for the bottom of the dump car 1. The movement of the dump doors 8-8 about the axes 7-7 is controlled. by certain link mechanism indicated as a whole by the numeral 9. Said link mechanism is controlledby the rotatable shaft 10 which in turn is controlled by the transversely ex tending shaft 11. The doors 8-8 may he, provided with .stifl'ening members 12-12 for preventing buckling of said doors. Said swinging doors 8-8 are provided with intermediate doors 18-13 pivoted for movement about the axes 1-1 1. Movements of the intermediate doors 13-13 about their axes 14-14 are controlled by the chains 15-15 which in turn are controlled by the longitudinally extending shafts 16-16. Movement of the doors 8-8 about their axes .7-7 will result in the dumping of lading from the car 1 between the tracks upon which the car is mounted. Movement of the doors 13-13 about their axes 1-14: will result in the dumping of lading outside of the tracks.

The link mechanism 9, by means of which movement of the doors 8-8 is controlled, need not he described in detail herein, insaid link mechanism do not constitute the present invention. It may be stated, however, that said link mechanism comprises two series of operating members, one series for each of the doors 8-8. Referring to Figure 2, it will be noted that the rotatable shaft 10 has secured thereto a crank arm 17 which operates through a series of links 18, 19 and 20 to control the right hand door 8. Referring to Figure 3 it will be noted that the rotating shaft 10 has fixed thereto the crank arm 21, which operates through links 22, 28 and 24 to control movement of the left hand door 8. Rotation of the shaft 10 in one direction will result in operation of the links 18, 19 and 20, and links 22, 23 and 24: to open both doors 8. -Operation of the shaft 10 in the reverse direction will result in the operation of said links to close the doors 8-8. As noted above, rotative movement of the shaft 10 is controlled by means of the transversely extending shaft 11.

The relative positions of the links when the doors are in fully opened positions and closed positions are indicated by dotted lines and full lines, respectively, in Figures 1, 2 and 3. A considerable degree of movement between link 20 and door 8 will occur during movement from one of said positions to the other of said positions. hen lading is being dumped from the car there is a possibility that part of said'lading willjlodge between the link 20 and the door 8, interfering with the subsequent closure of said door 8. In order to prevent any such posslble interference, the present invention contemplates the provision of certain protective means which will now be described.

The right hand door 8 has mounted there on near the swinging edge thereof the receptacle 25, which may be united to said door 8 by rivets or otherpreferred holding means. Said receptacle 25 provides a groove or channel 26 for the reception oi? a ii p or guard 27 located adjacent the lower extremity or the link 20. The receptacle 25 provides means for connecting the link 20 to the door 8, said link 20 being pivotally connected to the receptacle 25 by means of the pin 28. The lip 27 is adapted to ride at all times within the groove 26 provided by the receptacle 25 and will effectually prevent the lodging of lading in a position close to the pivotal connection between link 20 and door 8, thereby preventing such lading from interfering with the proper operation of said link 20 and door 8.

Non-rotatively mounted upon the operatin shaft 10 is the stop member .29. Said stop member 29 includes the two arms 17 and 21, each of which is bifurcated for the reception of a link. Said arms 17 and 21 are connected by the sleeve portion 32 having a cylindrical exterior whereby said member '29 may be rotatably supported by the strap 32, the ends of which may be connected to any suitable part of the car frame. It need not be stated that the'member 29 is non-rotatably mounted on shaft 10. The bitfurcated arm 17 provides a pivotal connec tion for link 18 and is provided with an abutment means or stop 33 adapted to cooperate with the link 18 or other member of the link mechanism for the right hand door 8. The bifurcated arm 21 provides pivotal connection for link 22 and is provided with an abutment means or stop 34 adapted to cooperate with link 22 or other member of the link mechanism for the left hand door 8. It will be clear, without detailed explanation that if. due to the strains encountered in service, the links constituting the operating mechanism for either or both of the doors '8'8 should tend to move too close to the center of rotation of shaft 10, that is to say, if said links should tend to move to inoperative positions, such movement will be effectually prevented by the stops or abutment members *33 and '34, which will engage said links and prevent same from moving to such inoperative positions. Said stops or abutment members 33 and 3% have the fimction, therefore, of holding the links for ope 'ating the doors S8 in proper spaced. relation relative to the axis of rotation of the operating shaft 10.

It will be at once understood that the lip 27 on the link 20, inasmuch as it operates at all times within the confines of'receptacle 25, will hold lading in spaced relation with the pivotal connection between said link 20 and the corresponding door 8, so that the danger of clogging between said link20and the corresponding door 8 will be substantially eliminated. Furthermore, by reason of the structure which holds the operating links always in proper spaced relation relative to the axis of rotation of theopera-ting shaft 10, danger eliminated of said links assuming encountered in service.

Although a preferred embodiment of the present invention has been described in detail, it will be clear to those skilled in the art that many modifications maybe made without departing from the spirit of the invention. It is intended in this patent to cover all such modifications thatffall within the scope of the appended claims.
